Special Issue Information

Dear Colleagues,

Innovative technologies have greatly impacted medicine by facilitating the early detection and staging of diseases, by guiding the development and selection of personalized treatment, and by offering efficient therapeutic modalities. Among the wide range of optical imaging approaches, such as point of care, wearable, bed-side/cot-side devices that can be used for diagnostic and monitoring therapeutic interventions, optical technologies, which encompasses microscopic, mesoscopic, and macroscopic optical imaging techniques, are emerging as powerful non-invasive modalities for functional and molecular imaging of in vitro, ex vivo, and in vivo specimens.

The scope of this Special Issue is to provide a source of information to review and share recent developments in novel optical technologies based on functional and molecular optical imaging techniques. We invite investigators to contribute original research and review articles that will stimulate the continuing translational efforts to bring optical imaging from the bench to the bedside. Sample includes but are not limited to:  

  • Rapid diagnostic optical technologies
  • Low-cost, easy to use optical technologies
  • Wearable optical devices
  • Point of care optical devices
  • Optical monitoring devices at the bedside, intensive care units

Transdermal optical wireless (TOW) communication links have recently gained particular research and commercial attention as a viable alternative for establishing high speed and effective implantable data transmissions, which is vital for a variety of neuroprosthetic and other medical applications. However, the development of this optical telemetry modality with medical implanted devices (IMDs) is adversely affected by skin-induced photon absorption, scattering and pointing errors effects. Thus, in this work a minimum mean-square error (MMSE) criterion is proposed for the estimation of the optical signal intensity in a typical TOW link of varying path loss and misalignment-induced fading characteristics. In this context, the stochastic nature of the transmitter–receiver misalignment has been considered and jointly modeled with transdermal path loss. Additionally, the link is assumed to employ the suitable On–Off Keying (OOK) with intensity modulation and direct detection scheme as well as a PIN photodiode at the receiver side for signal detection. Under these assumptions the results demonstrate that the stochastic amount of pointing mismatch strongly affects the received irradiance estimation. Full article
